Chan Ye Xin Xi Wang·2026-01-09 01:50Industry Overview - The Chinese network isolation gateway (网闸) industry is transitioning from compliance-driven to value-driven, with a market size projected to reach approximately 213.5 billion yuan in 2024, reflecting a year-on-year growth of 7.39% [1][4][8] - The network isolation gateway is a network security device that enables high-security data exchange through physical isolation and data ferrying technology, ensuring complete physical separation of networks while allowing controlled data exchange [2][4] Industry Development History - The development of the Chinese network isolation gateway has evolved through three stages: 1. First generation: Single machine isolation card technology for basic network isolation and non-real-time data exchange 2. Second generation: Switch and shared storage architecture addressing real-time issues 3. Third generation: Dedicated switching channel technology providing high-performance secure tunnels [4][5] Industry Chain - The upstream of the network isolation gateway industry includes raw materials and components such as chips, PCBs, high-speed solid-state switches, and power modules, as well as software like operating systems and security algorithms [5][6] Market Size - The market for the network isolation gateway is expected to grow significantly, driven by increasing data value and stringent cybersecurity requirements, with a projected market size of 213.5 billion yuan in 2024 [1][4][8] Key Companies' Performance - The competitive landscape of the network isolation gateway industry is characterized by leading companies like Qihoo 360 and Venustech, which dominate the market due to their technological advantages and established presence in critical sectors [8][9] Industry Development Trends 1. The technology will evolve towards a hybrid architecture that combines software-defined and hardware-accelerated solutions, enabling dynamic network isolation strategies [11] 2. The core value of network isolation gateways is shifting from mere network isolation to becoming comprehensive data security exchange platforms, integrating data security capabilities throughout the data lifecycle [12] 3. Future competition will focus on ecosystem and system capabilities, with a need for deep industry-specific solutions and a shift towards domestic hardware and intelligent software integration [13]
